Pembuatan Prototipe Alfa Gd Oksida dari Konsentrat Itrium
Abstract
Making alpha prototype of Gd Oxide from yttrium concentrates. A prototype of Gd oxide has been made from yttrium concentrate that produced by xenotime sand. The process is carried out by extraction and deposition. The solvent used for the extraction process is D2EHPA with kerosene as diluent, and the deposition process with ammonia. Feed of extraction is yttrium concentrate which is dissolved in nitric acid and the pH is set. Determination of Gd content and other rare earth metal impurities were analyzed using X-ray fluorescence. The purpose of this study was to obtain relatively pure of Gd oxide. The variable that influence the separation process of Gd: pH of the feed solution, extraction time, ratio of feed and organic phase. This reaserach is obtained Gd oxide concentrate 5.1613 grams with the content of Y2O3 = 13.24%, Gd2O3 = 22.28% and Dy2O3= 2.27%.
